wilwood caliper bleed nipple holder thread size
anybody know what size the thread is on the outside of wilwood caliper bleed nipple holders? I suspect its 3/8" unf but I'm hoping with
crossed fingers that they are 7/16"!!
I have £6000 worth of AP WRC calipers that some tossers have failed to recently open the bleed nipples on, or use anti-seize, or indeed fit new
waterproofing o-rings on on the occasion many millenia ago when they were last bled!! Consequently the bare steel nipples are now very much a part of
the caliper!! Particularly irratating as a company was paid to run the car!!
Drilling out and fitting adaptors is pretty much the only option left, as they are all shearing off, and even the mac tools extractor, plus ingersoll
rand titanium impact gun, won't shift the remnants (amazingly the mac extractor will stand the impact gun, but eventually it rips the inside
surface out of the bleed nipple without undoing it

Nat, these might work?

they do a 7/16 version too.
Also this is that other supplier I was talking about earlier, you might find them useful occasionally

send them back to ap and get them re worked then forward the bill to the offending company.
i have managed to drill right down the middle of a bleed nipple in the past to the point where there is very little of it left without damaging the
thread then get a very fine punch on the edge of the remnants and bash it inwards, may take a while but it works every time.

Very tempting, but I don't personally have enough background on the car's history. The owner just trusted them to sort the car, and paid
the bills when he got them.
We are now doing most of the work on it, having built it up (Steve Lancaster did the 'shell, and a FANTASTIC job of it too I have to say!) we
will be sorting it between events I think.
I have drilled through one of the bleed nipples, but the bottom section is so corroded in that it just won't loosen without risking damage to
the seat.
Have now found the wilwood thread sizes, M10 (no good) and 1/8 npt, (ideal! )
Will drill all the blled screws out, right through into the chambers, then drill and tap out the top section to 1/8npt and fit wilwood adaptors and
nipples to all of them, then reseal all the calipers!

Here's a pic of my Willwood nips broke twice while trying to remove them

I replaced the whole lot with a single one piece stainless bleed nipple, size on mine was m10 x 1.0
